(nor specify what circumstances). In my view this is one of the serious omissions in

Gore’s book.

similar view of this omission was taken by the judge in the UK court case

over Gore’s film and book.14 Indeed ‘Errors’ [His quotation marks].

T h e s h i f t i n t h e a r g u m e n t i s t h e i n c l u s i o the word permanently, making the comparison misleading. Indeed without specifying the time-scales, the comparison is meaningless. On the time-scales of tens of millions of years, the geological evidence suggests that the factor of 51 is too small. On timescales of millennia, geological analysis suggests that the factor is in the range 5 to 10. On n o f

the century timescale, the factor is closer to 2.

good conceptual analysis of these

issues is given by Eric Sundquist of the US Geological Survey in his chapter Geological perspectives on carbon dioxide and the carbon cycle [Plimer’s footnote 2117].

It mentions neither CO2 turnover, nor sediments. o r

The relevant d

chemical reaction is:

H2CO3 + CO

= 3

2HCO3

so that increasing CO2 (and thus H2CO3) tends to shift the balance to increasing 2HCO3

by removing CO

= 3

and so making carbonate sediments more soluble. (The conclusion

in reference 1738 was that this was not an immediate threat over significant areas of the ocean floor.)

14The judgement is at http://www.bailii.org/ew/cases/EWHC/ dmin/2007/2288.html. In versions prior to 2.1, before I rechecked the wording, the comment here about the judgement was noted as my recollection. Version 2.1 gave the URL incorrectly — thanks to Philip Machanik for pointing this out.

15In versions prior to 1.6, this issue was incorrectly noted as being on page 235.
